Bangkok's second largest airport will reopen this week after a more than four-month closure owing to the kingdom's worst floods in decades, an official said Monday.

"We are 100-percent ready to resume services on Tuesday," the general manager of Don Mueang International Airport in the north of the city, Kanputt Mungklasiri, told AFP.

The airport, which had been used for some domestic flights, suspended commercial operations in late October as the floods spilled into the capital.

The runways were submerged, but Kanputt said all the facilities had now been restored to normal.

So far, however, only Nok Air, one of the two main airlines previously operating at Don Mueang, has announced a move back from the main airport Suvarnabhumi, which is located to the east of the capital and was not flooded.

The other carrier, Orient Thai, plans to stay at Suvarnabhumi because it does not want to move its base again, the Bangkok Post English-language daily reported, quoting group founder Udom Tantiprasongchai.

The airport also doubled as a temporary evacuee shelter and a headquarters for the government's flood relief operation until it was inundated.

The months-long disaster killed hundreds of people, mostly in northern and central Thailand.
